bush and bill clinton before him. campaigns are about one vision of the world that is critical of their opponent, whether it is the incumbent or the previous president. for example, george w. bush on russia said bill clinton was wrong, he personalize our relationship, invested too much in boris yeltsin, and that is a disaster. i will be a realist, thinking about america's national interest, and what did he do? he got into office, met with vladimir putin, looked into his eyes, and famously saw his soul, so people pivot. events collide. things change. barack obama said he would negotiate with our enemies and our friends, and outlined a new policy of engagement to iran and north korea. those things did not happen. reality did not permit it. the record is running on would have astonished many supporters of barack obama in 2008. host: susan glasser is the editor in chief of "foreign policy magazine." here's a question from tony on twitter. the obama reset with russia, bush looking into platooned's soul neither worked well.
